Wind satellite vacuum packed
02 November 2017
With liftoff on the horizon, ESA's Aeolus satellite is going through its last round of tests to make sure that this complex mission will work in orbit. Over the next month, it is sitting in a large chamber that has had all the air sucked out to simulate the vacuum of space.
Aeolus carries one of the most sophisticated instruments ever to be put into orbit: Aladin, which includes two powerful lasers, a large telescope and very sensitive receivers.
